Plasma is the state that material is all ionized, and claims it to be the 4th state in addition to solid, liquid, gas in physics.
According to the particle temperature of plasma, plasma can be divided into two major classes, i.e. thermal equilibrium plasma and thermal nonequilibrium etc.
Gas ions.For relative thermal equilibrium plasma, the electronics tool of the plasma (also referred to as low temperature plasma) of nonequilibrium state
Having sufficiently high energy makes reactant molecule excite, dissociate and ionizes, and simultaneous reactions system can keep low temperature again, or even close to room
Temperature.
Microplasma be limited in a limited spatial dimension (yardstick be millimeter magnitude even lower) etc.
Gas ions, have had some characteristics of usual plasma concurrently, but because electric discharge size reduction is even lower to millimeter magnitude so that
Micro discharge plasma usually can run under atmospheric conditions.Microplasma is produced by atmospherical discharges.Electric discharge
Forming low temperature plasma form mainly has glow discharge, dielectric barrier discharge, corona discharge pulse, surface-discharge etc., wherein
It is dielectric barrier discharge and corona discharge pulse to study mostly must comparing.
Dielectric barrier discharge is a kind of typical nonequilibrium high-voltage alternating gas discharge.Wherein at least one electrode table
Face is coated with dielectric, and when two interpolars add ac high-voltage or pulse, the breakdown generation dielectric impedance of gas of two interpolars is put
Electricity.Dielectric barrier discharge is that in the presence of external electric field, electronics obtains energy from electric field, by with surrounding molecular atomic collision
Transmission energy, is allowed to excite ionization, produces electron avalanche, but the unlimited increasing of discharge current is limited due to dielectric impedance effect
It is long, only form fast pulse formula current filament passage, i.e., so-called micro discharge.Meanwhile, dielectric can also prevent electric discharge to arc light
The transition of electric discharge, it is possible to achieve atmosphere gas are discharged, thus just by it is increasingly extensive be applied to ozone synthesis, high-power purple it is outer,
The field such as water process and environmental protection.
